Lesson 19 — Capital Gains Tax and International Taxation in Zimbabwe

Executive summary — 16 Mar 2026

Zimbabwe’s Capital Gains Tax (CGT) system is conceptually source-based: the core charging base (“gross capital amount”) is defined as amounts received or accrued “from a source within Zimbabwe” on sales (and certain deemed sales) of specified assets. This design makes nexus (source) analysis the first gate for cross-border CGT problems, before moving to administration (withholding, clearance, filing, payment) and then to treaty override where a Double Taxation Agreement (DTA) applies.

International practice issues in Zimbabwe CGT are dominated by: (i) non-resident disposals of Zimbabwean immovable property and Zimbabwe-linked securities; (ii) collection at source through Capital Gains Withholding Tax (CGWT) operated by depositaries (conveyancers, stockbrokers, financial institutions) with strict 3 working day remittance rules; and (iii) registration/transfer blockages unless proof is produced that CGT has been paid (or otherwise dealt with), which is critical for property and share transfers.

Treaties matter in two distinct ways. First, the CGT Act imports the Income Tax Act’s treaty proclamation mechanism (section 91) into CGT, placing DTAs at the center of formal double taxation relief for capital gains. Second, individual treaties can allocate taxing rights over capital gains very differently (immovable property gains almost always taxed in Zimbabwe as the situs state; gains on ordinary shares often reserved to the seller’s residence state unless “property-rich” share rules apply).

A practitioner’s international CGT workflow in Zimbabwe therefore has four checkpoints:
(1) Is the asset a “specified asset” and is the gain Zimbabwe-source?
(2) Does a DTA cover “taxes on capital gains” and allocate taxing rights away from Zimbabwe?
(3) If Zimbabwe may tax, how will CGWT be withheld and credited/refunded?
(4) What clearance/registration steps (TaRMS) must be completed to close the transaction?

Learning objectives and key concepts

By the end of this lesson, advanced students and practitioners should be able to:

1. Apply Zimbabwe’s nexus (source) test for capital gains to cross-border disposals, using statutory definitions and administrative enforcement realities (registration, withholding).
2. Distinguish treatment of non-resident disposals of:
3. Immovable property (including land development schemes, cessions, and condominium interests), and
4. Marketable securities (listed vs unlisted).
5. Map CGWT collection mechanics (depositary obligations, clearance certificates, remittance timing, and credit/refund outcomes), including the special timing rules for suspensive conditions and credit sales.
6. Analyze how DTAs override domestic outcomes, including: residence tie-breakers, capital gains allocation articles, elimination of double taxation (credit/exemption), and mutual agreement procedures.
7. Execute (and audit-proof) a cross-border CGT file: documentation, TaRMS clearance verification, withholding certificates, and—where relevant—treaty relief claims and refunds.

Key statutory anchors used throughout this lesson include: charging and definitional rules in the CGT Act (notably sections 6 and 8), special timing rules in sections 18–19, roll-over provisions in sections 15/17/22, withholding rules in Part IIIA, payment timing in section 26, registration restrictions in section 30A, treaty linkage in section 28, and anti-avoidance linkage in section 29.

Domestic legislative framework for cross-border CGT

Statutory basis and the Zimbabwe nexus

Zimbabwe CGT is charged on capital gains received by or accrued to any person during a year of assessment. The international “hook” is not framed as “residence-based worldwide taxation,” but rather through the statutory definition of gross capital amount: amounts received or accrued “from a source within Zimbabwe” from sales (and certain deemed sales) of specified assets.

A specified asset includes (among other categories):
- Immovable property,
- Any marketable security (shares, bonds, stock, debentures, unit trusts) whether or not quoted/traded, and
- Expanded categories such as certain rights and registrable property interests.

Analytical implication: in cross-border matters, you generally test Zimbabwe’s assertion of CGT in this order: 1) asset is a “specified asset”;
2) disposal gives rise to a capital amount;
3) the amount is Zimbabwe-source; and then
4) treaty relief (if any) is applied to modify or eliminate Zimbabwe’s taxing right.

Source rules by asset class

The CGT Act itself uses the phrase “source within Zimbabwe” but does not, in the CGT Act text alone, provide an exhaustive stand-alone source code for gains comparable to a modern “situs” chapter. In practice and enforcement design, nexus is strongest where Zimbabwe can control transfer and registration.

Immovable property in Zimbabwe and Zimbabwe-registrable land interests

For land/buildings and other Zimbabwe registrable rights (including stands and certain condominium interests), the situs/registration link is the operational nexus because transfer is blocked unless ZIMRA certification is produced (see section 30A mechanics below).

Shares and marketable securities

“Marketable security” is defined expansively, and depositaries for securities include stockbrokers, financial institutions, and other persons holding sale proceeds pending transfer. Zimbabwe therefore often enforces nexus via the intermediated settlement chain (withholding at source and documentation) rather than through physical situs.

Explicit cross-border reach: special mining-title CGT

A major modern cross-border feature is section 30B (“special capital gains tax on the transfer of a mining title”), which applies to very broad classes of entities including those domiciled outside Zimbabwe, and explicitly reaches transactions concluded “within or outside Zimbabwe.” This provision is a standout because it can pull extra-territorial transactions into Zimbabwe’s CGT net even when other Zimbabwe-source tests might be debated.

Currency of gains and cross-border pricing

The Finance Act establishes a foreign-currency payment regime for capital gains: where capital gains are received/accrue in foreign currency, CGT is payable in foreign currency on the portion received/accrued in foreign currency, with separate computations where only part is in foreign currency. This frequently matters for non-resident sellers (common settlement currency USD) and for treaty credit computations abroad.

Domestic anti-avoidance relevance for treaty-shopping and structuring

The CGT Act expressly incorporates the Income Tax Act’s general anti-avoidance rule (GAAR) by applying section 98 of the Taxes Act to CGT matters. This is the domestic statutory basis for challenging artificial cross-border CGT arrangements (including some treaty-shopping or contrived valuation structures), independent of treaty anti-abuse clauses.

Treaty interaction and double taxation relief

Treaty incorporation into CGT: the statutory bridge

The CGT Act applies the Income Tax Act’s double taxation agreement mechanism to CGT via section 28, which applies section 91 of the Taxes Act (Income Tax Act) mutatis mutandis to CGT. Under section 91, the President may enter into agreements for avoidance of double taxation and then proclaim them; once proclaimed, the agreement has effect “as if enacted” in the Income Tax Act. Read together with the CGT Act bridge, this is the principal statutory route by which DTAs can limit Zimbabwe CGT.

How DTAs resolve capital gains: allocation rules

Zimbabwe treaties (like most international models) commonly allocate:

• Immovable property gains: usually taxable in the state where the property is situated (Zimbabwe for Zimbabwe land).
• Shares / interests: frequently taxable only in the seller’s residence state unless the company is “property-rich” (value derived principally/over 50% from immovable property in the source state).
• Other property (not caught by special rules): often taxable only in the seller’s residence state.

Worked treaty illustration: Zimbabwe–South Africa DTA
In the Zimbabwe–South Africa DTA, “capital gains” are addressed under ARTICLE 14 (CAPITAL GAINS), which grants the source state taxation rights over immovable property gains, PE-related property, and certain property-rich share disposals, while allocating other gains to residence. The same treaty includes a notable rule allowing the former state of residence to tax certain share gains for a period after change of residence (a “migration” style rule).

Determining treaty residence: tie-breakers and entities

Treaty residence is not assumed from domestic labels; it is determined under the treaty’s residence article, then tie-breakers apply for dual residence.

• Under the Zimbabwe–South Africa treaty, dual-resident individuals are resolved through permanent home/centre of vital interests/habitual abode/nationality/mutual agreement steps.
• Entity residence tie-breakers may depend on the specific treaty. The Zimbabwe–Switzerland agreement text, for example, provides a corporate tie-breaker based on place of effective management.

Elimination of double taxation: credit vs exemption and why it matters for CGWT

Treaties typically eliminate double taxation using either credit or exemption methods (sometimes a hybrid).

• Under the Zimbabwe–South Africa DTA, ARTICLE 22 (ELIMINATION OF DOUBLE TAXATION) provides a credit-method structure for Zimbabwe (crediting South African tax against Zimbabwe tax) and similarly for South Africa.
• Under the Zimbabwe–Switzerland agreement text, ARTICLE 22 contains an exemption method in Switzerland for certain income (with progression), with important conditions for some gains (e.g., requiring demonstration of actual taxation in Zimbabwe for certain gains), and also provides Swiss credit/relief mechanics for specific passive income categories.

Practical CGT point: even if Zimbabwe collects CGWT up-front, treaty relief is typically implemented either by (a) preventing withholding through a clearance process, or (b) allowing refund/credit after the fact. Zimbabwe’s CGT Act provides domestic refund and credit mechanisms for over-withholding.

Mutual agreement procedure and dispute channels

Treaties generally offer a mutual agreement procedure (MAP) to resolve cases of taxation not in accordance with the treaty.

• The Zimbabwe–South Africa DTA includes a MAP article allowing the taxpayer to present a case and requires competent authorities to endeavour to resolve it; any agreement reached must be implemented notwithstanding domestic time limits.
• The Zimbabwe–Switzerland agreement text similarly includes MAP language and direct competent authority communication provisions.

Procedural mechanics for cross-border transactions

Withholding as the collection engine: who withholds and when

Who is a “depositary”

A “depositary” is defined widely and includes, for example:
- For immovable property: conveyancer, legal practitioner, estate agent or similar person holding sale monies for a seller; building societies; Sheriff/Master for execution sales.
- For marketable securities: stockbrokers, financial institutions, or other persons holding proceeds pending transfer.

International implication: non-residency of the seller does not remove the depositary’s withholding responsibility; the withholding duty is transaction- and role-based.

Core remittance deadline

Depositaries paying amounts to the seller must withhold CGWT and pay to ZIMRA no later than the 3rd working day from payment date (unless extended for good cause).

Filing/credit consequence

Where tax is withheld, the depositary must issue the payee a prescribed certificate with names, property particulars, and tax withheld.

Rates and classification: property vs listed vs other securities

Zimbabwe’s Finance Act (as updated to 1 Dec 2024) sets differential CGT and CGWT rates:

CGT rates

For specified assets acquired after 22 Feb 2019, CGT is 20% of the capital gain (expressed as $0.20 per dollar of gain or US$0.20 per US$ of gain, depending on currency rules).
For specified assets acquired before 22 Feb 2019, CGT is 5% of the gross capital amount (proceeds), not the computed gain.

CGWT rates (key cross-border ones)

• Listed marketable securities: 1% of sale price, treated as final tax (not merely a prepayment/withholding).
• Note: the Finance Act text records a temporary period where listed-security CGWT was treated as a 2% final tax for six months from 28 June 2024, during which “no CGT would be applicable” (as reflected in the explanatory note preserved in the consolidated text).
• Immovable property acquired after 22 Feb 2019: the consolidated text provides a provisional withholding mechanism tied to the gain and subject to final assessment at 20% (with specific rates depending on whether the case is a local-currency or foreign-currency computation).
• Other marketable securities (non-listed): 5% of sale price.

Timing for cross-border contracts: suspensive sales vs credit sales

Suspensive-condition sales of immovable property: section 18

Where an agreement provides that ownership passes upon/after receipt of all or a portion of the amount payable, the whole amount is deemed to have accrued on the date the agreement is entered into, but the Commissioner deducts an allowance computed by the statutory formula:

$$\text{Allowance} = \frac{A \times \left( B - C \right)}{D}$$

where A is the portion not receivable at year-end, B is the capital amount deemed accrued, C is certain allowable deductions, and D is the amount deemed accrued.

Payment due date linkage: CGT becomes due within 30 days from the date when a specified asset dealing under section 18(1) accrues under those provisions (unless an earlier withholding deadline applies).

Credit sales where ownership passes: section 19

Where ownership passes on delivery but the price is payable in instalments, the whole amount is likewise deemed to accrue at contract date, but the Commissioner may deduct a reasonable allowance for instalments not receivable by year-end, with carryover inclusion the following year; certain deductions are expressly disallowed in such cases.

Registration and closing: the “no certificate, no transfer” rule

Section 30A blocks execution/attestation/registration of transfers (including property transfers by the Registrar of Deeds and transfer of shares in companies registered/incorporated under the Companies and Other Business Entities Act) unless a ZIMRA certificate is submitted confirming CGT payable has been paid.

Practical cross-border consequence: non-resident sellers cannot “leave the country and sort tax later” if the transaction requires Zimbabwe registration—closing is often hostage to the CGT certificate.

TaRMS and authenticity controls

ZIMRA has migrated clearance administration into TaRMS. With effect from 1 August 2024, electronic CGT clearance certificates with an authentication code and QR code can be validated on TaRMS; manual CGT clearance certificates were discontinued.

ZIMRA has also published guidance on verifying online CGT clearance certificate authenticity, reinforcing that transaction parties should validate certificates to combat fraud.

Documentary requirements: cross-border seller representation

ZIMRA lists typical documentation for CGT clearance processing including: a completed CGT1, REV1, agreement of sale, deed/share certificate, proof of payment, IDs, and—critically for international sellers—a notarised power of attorney when the buyer/seller is out of the country and represented.

Worked numerical examples with calculations and assumptions

All examples assume the asset was acquired after 22 Feb 2019, so the final Zimbabwe CGT rate is 20% of capital gain (unless otherwise stated).
Currency assumptions are highlighted because foreign-currency payment rules can change computational mechanics.

Example one — Non-resident sells Zimbabwe immovable property under a suspensive sale

Facts (assumptions):
A South African resident individual sells a Harare property (immovable property in Zimbabwe) for US$500,000.
Cost base and allowable costs: purchase price US$200,000, improvements US$30,000, legal/transfer costs US$20,000.
Suspensive terms: purchaser pays US$100,000 on signing; remaining US$400,000 payable on transfer 9 months later.
No exemption applies.

Step 1 — Identify the timing rule (section 18)
The contract is a suspensive sale where ownership passes upon receipt of a portion/whole of the price. The whole amount is deemed to accrue at contract date, subject to the statutory allowance formula.

Step 2 — Compute capital gain (final assessment basis)
Proceeds (sale price): 500,000
Less allowable cost base: 200,000 + 30,000 + 20,000 = 250,000
Capital gain = 500,000 − 250,000 = 250,000

Final CGT (20% × 250,000) = US$50,000.

Step 3 — Apply the section 18 accrual allowance (deferral across years)
At end of the year of assessment, assume the seller has not yet received A = US$400,000.
Assume B (capital amount deemed accrued) = US$500,000 and C (sum of allowable deductions for the asset) = US$250,000 and D (amount deemed accrued) = US$500,000.
Allowance = A × (B − C) / D = 400,000 × (500,000 − 250,000) / 500,000
= 400,000 × 250,000 / 500,000
= US$200,000 allowance.

Interpretation: the allowance is deducted in the first year and then included as capital amount in the next year, deferring part of the taxable amount to the year when proceeds are received/closing occurs.

Step 4 — Withholding and payment timing implications
- CGT is generally due within 30 days under the section 18/19 timing rule (unless an earlier withholding deadline applies).
- If a depositary pays proceeds to the seller, CGWT must be remitted within 3 working days of that payment.

Illustrative CGWT computation (provisional withholding + final top-up)
For immovable property acquired after 22 Feb 2019, the consolidated Finance Act text provides for a provisional withholding subject to final assessment at 20%.
Assume the applicable provisional withheld amount on the gain is US$0.05 per US$ of gain (as stated in the consolidated text for the foreign-currency case), i.e. 5% of capital gain.

Provisional withholding = 5% × 250,000 = US$12,500.
Final CGT = US$50,000.
Balance payable after credit = 50,000 − 12,500 = US$37,500.

Treaty check (Zimbabwe–South Africa DTA):
The treaty generally permits Zimbabwe to tax gains from alienation of immovable property situated in Zimbabwe.
Therefore, treaty relief is typically a credit in South Africa, not an exemption from Zimbabwe CGT.

Example two — Non-resident sells shares in a Zimbabwe company (listed vs unlisted) and treaty interaction

Listed shares (ZSE trade): CGWT as final tax

Facts:
A South African resident sells listed shares on the Zimbabwe Stock Exchange for US$200,000. Ignore brokerage for simplicity.

Zimbabwe CGWT (listed securities):
CGWT is 1% of sale price and is treated as final tax under the consolidated Finance Act.
CGWT = 1% × 200,000 = US$2,000.

Treaty analysis:
Under many treaty formulations, gains on ordinary shares not linked to immovable property may be taxable only in the seller’s residence state.
However, because Zimbabwe domestic law treats listed-security CGWT as a final tax, treaty-position planning must be done pre-trade (typically through applying for a clearance mechanism or refund route). Zimbabwe domestic law provides for refund where CGWT is overpaid and for interest if not refunded within 60 days of a valid timeline, subject to a six-year claim limit.

Practical note: The statutory procedure for “treaty-based reduction at source” in CGWT is not expressly specified in the CGT Act text; practitioners commonly manage this risk by (i) seeking a clearance certificate on the basis that no CGT is likely payable (including by treaty) before payment is made, or (ii) paying and later seeking refund with documentary proof of treaty entitlement.

Unlisted shares (private sale): CGWT as prepayment and final CGT assessment

Facts (assumptions):
A non-resident sells shares in a private Zimbabwe company for US$300,000.
Base cost US$120,000; transaction/legal costs US$10,000.
Capital gain = 300,000 − 130,000 = 170,000.
Final CGT (20%) = 34,000.

Withholding on “other marketable securities”:
CGWT is 5% of sale price.
CGWT withheld = 5% × 300,000 = 15,000.

Credit against final CGT:
CGWT paid is credited against final CGT; any excess is refunded.
Balance due = 34,000 − 15,000 = 19,000 (payable within required payment timeframe).

Treaty overlay:
If a treaty allocates taxing rights on these shares to the seller’s residence state (and the company is not “property-rich” under the treaty test), Zimbabwe’s right to tax may be limited.
In that case, the non-resident’s operational options remain: clearance up front, or refund later—supported by Zimbabwe’s refund provision in section 22I (six-year claim).

Example three — Cross-border corporate restructuring with roll-over and treaty considerations

Scenario:
ForeignCo (incorporated outside Zimbabwe) carries on its principal business inside Zimbabwe and is being voluntarily wound up in its country of incorporation. It transfers the whole business and property (including a Zimbabwe property) to NewCo, and the sole consideration is share issuance to ForeignCo’s members proportionate to their holdings; no outside investors receive shares.

Statutory roll-over route:
Section 15(1)(a) allows an election for such a transfer (foreign incorporated company winding up to transfer whole business/property) such that the selling price is deemed to equal the transferor’s tax cost (sum of allowable deductions), producing no immediate CGT, and on later sale outside the group the gain/loss is computed as if the asset had remained in the ownership of the first transferor.

Numbers (assumptions):
Zimbabwe property original cost: US$1,000,000.
Transferred to NewCo at roll-over (no immediate CGT).
Two years later NewCo sells property to an unrelated purchaser for US$1,800,000.

Future disposal trigger:
Gain = 1,800,000 − 1,000,000 = 800,000
Final CGT (20%) = 160,000.

Treaty interaction:
If NewCo is Zimbabwe resident, Zimbabwe taxation is straightforward. If NewCo is treaty-resident elsewhere (unusual for a Zimbabwe-incorporated company but possible depending on domestic/treaty residence definitions), the treaty’s immovable property gain rule commonly still preserves Zimbabwe’s taxing right as the situs state.

Pitfalls, anti-avoidance, and exam practice

Common pitfalls and audit triggers in cross-border CGT

Misclassifying gains as “non-taxable because the seller is non-resident” is a frequent error; Zimbabwe’s regime is source/asset based and reinforced through registration and withholding mechanisms.

Treaty relief mistakes commonly include:
- Assuming a treaty applies without confirming whether it covers taxes on capital gains and whether it is in force for Zimbabwe CGT purposes, when the CGT Act relies on the treaty proclamation mechanism.
- Failing to document treaty residence and property-rich tests, leading to withholding that cannot be efficiently refunded.

Documentation/closing failures:
- Not preparing notarised powers of attorney for non-resident buyers/sellers represented locally (explicitly listed by ZIMRA for CGT clearance processing).
- Accepting “manual” CGT clearance certificates after the discontinuation date, or failing to validate TaRMS certificates (fraud risk).

Anti-avoidance and treaty-shopping lens

Zimbabwe’s domestic CGT imports the Income Tax Act’s tax avoidance provision (section 98) into CGT.
Separately, newer treaty texts can include explicit anti–treaty-shopping intent language—e.g., the Zimbabwe–Switzerland agreement text expressly states it is intended to avoid double taxation without creating opportunities for reduced taxation through treaty-shopping.

Exam-style questions with model answers

Question 1 (nexus + treaty):
A UK resident sells shares in a Zimbabwe company that holds only operating assets (not immovable property) and receives US$1 million. Zimbabwe stockbroker withholds 1% CGWT because shares are listed. The seller claims the DTA allocates taxing rights to the UK. Advise on Zimbabwe compliance steps.
Model answer (outline): Identify domestic law: listed-security CGWT is final tax at 1% of sale price. Because withholding occurs at source, treaty relief is typically pursued (i) via a pre-payment clearance strategy where “no CGT is likely payable” and adequate arrangements exist, or (ii) via refund under section 22I upon proof that the tax was in excess of the amount properly chargeable (treaty override), subject to the six-year claim window. The seller should retain depositary certificate and treaty residence evidence; if refund is delayed beyond statutory timeframes, interest may be payable.

Question 2 (suspensive sale timing):
A non-resident sells Zimbabwe land under a contract where transfer occurs only after full payment; buyer pays 10% now, 90% next year. When does CGT become due?
Model answer (outline): Section 18 deems the whole amount to accrue at contract date; section 26 makes tax due within 30 days from accrual under section 18 (subject to earlier withholding triggers). The statutory allowance formula defers part of the capital amount to the next year if amounts are not receivable at year-end.

Question 3 (cross-border restructuring):
A foreign-incorporated company with principal business in Zimbabwe is wound up in its home jurisdiction and transfers all business and property to a Zimbabwe company for shares issued to its members. Explain the relief and the later-disposal consequence.
Model answer (outline): Section 15(1)(a) provides a roll-over election. Selling price is deemed to equal tax cost (sum of allowable deductions), producing no immediate CGT; on later sale outside the group, gain/loss is calculated as if the asset remained with the original transferor.
